Wearing resistant refractory plastic
Hongtai produce various kinds of wearing resistant refractory plastic, including corundum mullite plastic refractory, silicon carbide plastic refractory and other high quality refractory plastic.
Wearing resistant refractory plastic is bulk refractory, its main raw materials are calcined refractory aggregate, fireclay, and other binders, they are mixed and tempered to plastic bodies.
During construction, pneumatic hammer or manual hammer can be used to ram it into any shapes and thickness.
